The Connection Between Contact Lens Wear and Dry Eye

Wearing contact lenses offers many people the convenience of clear vision without the hassle of glasses. However, for some wearers, contact lenses can lead to or worsen symptoms of dry eye syndrome. Understanding this connection is essential for maintaining both comfort and eye health.

How Contact Lenses Affect Tear Film

Your tear film - the thin layer of moisture that coats the surface of your eyes - is vital for keeping them lubricated and comfortable. Contact lenses rest directly on this tear film, and in doing so, they can disrupt its natural balance. When the tear film evaporates too quickly or fails to fully cover the lens surface, the eyes may feel dry, gritty, or irritated.

Common Symptoms of Dry Eye in Contact Lens Wearers

If you wear contact lenses and experience any of the following, you may be dealing with dry eye:

• Redness or irritation after a few hours of wear

• Blurry or fluctuating vision

• A feeling of grittiness or burning

• Increased sensitivity to light

• The urge to remove your lenses early in the day

Why Contact Lens Wear Can Contribute to Dry Eye

Several factors can make contact lens wearers more prone to dryness:

• Reduced oxygen flow: Contacts limit the amount of oxygen reaching the cornea, which can affect tear production.

• Lens material: Some lenses, especially older hydrogel types, retain less moisture.

• Wearing time: Extended wear or wearing lenses beyond their recommended replacement schedule can cause irritation.

• Environment: Air conditioning, heating, and prolonged screen use can all dry out the eyes faster.

Managing Dry Eye While Wearing Contacts

You don’t necessarily have to give up your contact lenses if you have dry eye. With the right management, comfort can be restored:

• Use rewetting drops: Opt for preservative-free lubricating drops safe for use with contacts.

• Upgrade your lenses: Newer silicone hydrogel or daily disposable lenses are designed to enhance oxygen flow and retain moisture.

• Take breaks: Alternate between contacts and glasses to give your eyes time to recover.

• Address underlying causes: If dry eye persists, your optometrist may recommend professional treatments such as meibomian gland therapy, punctal plugs, or specialized eye drops to improve tear quality.
